Initiation of a 5-Year Review of Aleutian Shield Fern (Polystichum aleuticum)

The U.S. Fish and Wildlife Service (Service) announces a 5- year review of Aleutian shield fern (Polystichum aleuticum) under section 4(c)(2)(A) of the Endangered Species Act of 1973 (Act) (16 U.S.C. 1531 et seq.). A 5-year review is a periodic process conducted to ensure that the listing classification of a species is accurate. A 5-year review is based on the best scientific and commercial data available at the time of the review; therefore, we are requesting submission of any such information on Aleutian shield fern that has become available since its original listing as an endangered species in 1988 (53 FR 4626). Based on the results of this 5-year review, we will make the requisite finding under section 4(c)(2)(B) of the ESA.
